Not a student, but I do appreciate the hints! In my case I need it to work for positive real values of x and values of n=y/2 where y is a positive integer. As for why this comes up: I'm working on a statistical estimation problem and this is part of the normalization term in my log-posterior. Again, thanks for the hints. I'll try my hand at solving it.
